2. RF modulator - Wikipedia

   en.wikipedia.org/wiki/RF_modulator

   An RF modulator (radio frequency modulator) is an electronic device used to convert signals from devices such as media players, VCRs and game consoles to a format that can be handled by a device designed to receive a modulated RF input, such as a radio or television receiver. Its input is a baseband signal, which is used to modulate a radio ...

3. 8VSB - Wikipedia

   en.wikipedia.org/wiki/8VSB

   8VSB. 8VSB is the modulation method used for broadcast in the ATSC digital television standard. ATSC and 8VSB modulation is used primarily in North America; in contrast, the DVB-T standard uses COFDM. A modulation method specifies how the radio signal fluctuates to convey information. ATSC and DVB-T specify the modulation used for over-the-air ...

4. QAM (television) - Wikipedia

   en.wikipedia.org/wiki/QAM_(television)

   QAM (television) QAM is a digital television standard using quadrature amplitude modulation. It is the format by which digital cable channels are encoded and transmitted via cable television providers. QAM is used in a variety of communications systems such as Dial-up modems and WiFi. In cable systems, a QAM tuner is linked to the cable in a ...

5. Modulation - Wikipedia

   en.wikipedia.org/wiki/Modulation

   Passband modulation. In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. [1] For example, the modulation signal might be an audio signal ...

6. Video modulation - Wikipedia

   en.wikipedia.org/wiki/Video_modulation

   Video modulation. Video modulation is a strategy of transmitting video signal in the field of radio modulation and television technology. This strategy enables the video signal to be transmitted more efficiently through long distances. In general, video modulation means that a higher frequency carrier wave is modified according to the original ...

7. Frequency-division multiplexing - Wikipedia

   en.wikipedia.org/wiki/Frequency-division...

   t. e. In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal. This allows a single transmission medium such as a microwave radio link, cable or ...
